Cool find and a very interesting analysis!
There's a lot more to morphology than just the shape of the shell, and indeed the shape can sometimes be misleading, in that very different species can have somewhat similar shells, and different individuals of the same species can have quite different shell shapes. You've got a gasteropod, so it would be good to pay special attention to the peristome and siphonal canal (based on the bio classes I took in the area, I'm no expert) but of course there's lots of features that could be helpful in an identification.
https://en.wikipedia.org/wiki/Gastropod_shell#Parts_of_the_s... is a good list, and maybe you've already done this but you would want to find a dichotomous key of gasteropod families native to the area to narrow it down. Good luck in figuring out your shell!

“A brief tale of how I got AI psychosis after I mistook pareidolia for a fossil”
I’m more interested in the giant face carved into the rocks in the second photo. Does this person not realise they’ve discovered a previously unknown sculpture of Yahoo-Wahoo?

Huh? Plenty of places have geology where the rocks were formed under ancient oceans and are full of sea fossils.

Maybe. But I don’t see anything in this piece that says that it’s a fossil, rather than something that resembles this person’s idea of a fossil. It doesn’t look like a fossil to me. It looks like a piece of rock that’s been bashed about a bit.
And given the whole premise of the piece is “this should not be here!” I don’t really understand the point you’re making. The author says it’s a strange find in that area - so either they have a valid point or they don’t.
I don’t know if it’s a fossil. It doesn’t look like a fossil to me. I’m not a fossil expert. The only way to tell if it is a fossil is to do some analysis on the actual specimen before writing screeds about what it might or might not be based on visual similarity.

Author points out themselves, in the second paragraph, that its not a strange find. The strangeness of the find is his personal experience. Not that its a strange find geologically.

If we're going to rate annoying takes on the internet, "some guy who knows nothing about a topic being snarky because AI was involved" is far worse than somebody doing something with AI.

Guy?
And I think you’re arguing yourself into a hole here.
What makes you think I know nothing about the topic? I have donated - at their request - three fossils to national museums.

Maybe some geology buffs can correct me, but as I understand it there has been three periods with ocean on top of the crust we call Pakistan today. The Proto-Tethys, Paleo-Tethys, and Tethys Ocean. Many hundreds of millions of years of being ocean.

Because of the Indian subcontinent colliding with the Eurasian plate there's a wide variety of origins for the surface geology in that region.
I guess He didn't see the Reddit post in R/SaudiArabianDesertLostandFound
> "if anyone finds my lucky seashell that I lost, could you please return it. I think I lost it near the Alghat desert while I was sledding down a sand dune.

She sells seashells in the Sahara was my first association, but then the article clearly states that we're talking about a different desert.

Looks like ampullospira, documented in Saudi Arabia. Age (middle-upper Jurassic) and actual location also match.

What a ridiculous place to put a blog. Why is this on github?
mik3y 1 hours ago [-]
Because the repo includes the tool authored for, and discussed in, the "blog"?
Not saying its a good idea, but blogging on github has been a thing for much over a decade by now.

I don't understand why the author didn't put all of these pictures and information of where he found it into an AI like ChatGPT. That should be the first thing one should try.

Among a strong field, this is the single most depressing comment I’ve ever read on Hacker News. Several grim components but it’s the “I don’t understand why” which seals the deal.

Why? Calling a reasonable thing grim without any follow-up isn’t the hallmark of a good comment either.

I trust a proper solution (even though I can be certain how accurate it is), which compares to a known dataset much more than just giving it an AI. For identifying current living species it is probably fine but this is something to nice for an AI to be trustable. Also this path is much more fun and you learn sonething along the way!

but, from my understanding what the author was really wanting was an adventure and to learn new things. he gained so much more than just learning what type of shell it is

Who says the whole analysis isn’t AI inspired?

The AI would confidently give him the wrong answer, since it has no way to provide the correct answer, and doesn't know its own limitations. (Or however you wish to describe "hallucinations", which is about as accurate as my description ;))
And he would think he has the right answer, perhaps write up an essay about his findings, which later AI bots will read and learn from, propgating the mistake...
